In 2023, we deprecated the Simple UI, but kept the Variant Sets thumbnail preview, adding a Switch Display Mode option to the Variant Sets module.
In the Variant Sets module, to change the display, either right-click and select Switch Display Mode or click in the Icon Bar.
To return to the previous display, either right-click and select Switch Display Mode or click .
For more information on using the thumbnail display, see the Variant Set Thumbnail Display section of Variant Sets.
